Hamstring injuries are one of the most frustrating setbacks for track and field athletes. Sprinters, hurdlers, and jumpers rely heavily on strong hamstrings for explosive movement, and even a small strain can take them out of training or competition for weeks. The pain itself is difficult, but the real challenge often comes from the long recovery time and the risk of the injury returning.
Physiotherapy provides a structured path forward, which heps athletes manage pain, rebuild strength and restore full speed safely. AlphaOne Physio is a leading physiotherapy clinic in Calgary.

What is a Hamstring Injury? Anatomy and Function in Sprinting & Jumping
The hamstrings are a powerful trio of muscles: the biceps femoris, semitendinosus and semimembranosus. They sit at the back of the thigh and work together to bend the knee and extend the hip, making them essential for sprinting, jumping and explosive athletic movements.
In track and field: These muscles are under constant demand.
- During sprinting, they work eccentrically to decelerate the leg just before the foot strikes the ground.
- During hurdles and jumps, they lengthen quickly to stabilize and power explosive movements. This combination of high speed, lengthening under tension, and repetitive force makes the hamstrings highly vulnerable to injury.
Types and Characteristics of Hamstring Injuries
Sprinting-related strains:
- Occur in the terminal swing phase of sprinting.
- Most often involve the biceps femoris long head.
- Typically causes sharp, sudden pain.
Stretch-related strains:
- Common in hurdlers, jumpers, and dancers.
- Involve the hamstring in a stretched position, especially the semimembranosus tendon.
- May look less severe at first but often take longer to heal.
Chronic tendinopathy:
- Develops from repeated stress and insufficient recovery.
- Leads to persistent pain at the hamstring tendon, especially near the sit bone (ischial tuberosity).
Understanding the type of hamstring injury is critical, as each follows a different healing timeline.
Grading Hamstring Strains and Recovery Time
| Grade | Attribute (Severity) | Attribute (Symptoms) | Value (Recovery Time) |
|---|---|---|---|
| Grade 1 | Mild strain | Tightness, slight discomfort, minimal fiber damage | 1–2 weeks |
| Grade 2 | Partial tear | Bruising, swelling, pain when walking | 4–8 weeks |
| Grade 3 | Complete tear | Severe pain, loss of function | 3–6 months |
Hamstring strains are typically classified into grades:
- Grade 1: Mild strain, minimal fiber damage. Athletes often recover within 1–2 weeks.
- Grade 2: Partial tear, swelling, bruising, and reduced strength. Usually requires 4–8 weeks of recovery.
- Grade 3: Complete rupture, severe pain, and loss of function. Recovery can take several months, and in some cases, surgery is required.
A 2016 systematic review in the British Journal of Sports Medicine concluded that imaging alone cannot predict recovery time from hamstring injuries. Instead, clinical assessment and functional testing provide more reliable guidance for determining when an athlete is ready to return to sport.
Causes and Risk Factors in Track & Field
Hamstring injuries are complex and multifactorial, rarely occurring without an underlying cause. Research shows they often stem from a combination of mechanical stress, muscular imbalances, and training-related factors all contribute to the likelihood of injury. The following key elements are commonly associated with hamstring strains in track and field athletes:
- Sudden acceleration or deceleration in sprints.
- Muscle imbalances, especially weak hamstrings compared to powerful quadriceps.
- Poor lumbopelvic control, leading to faulty sprint mechanics.
- Fatigue, which reduces coordination and increases strain.
- Inadequate warm-ups or skipping mobility drills.
For track athletes, this means both performance load and training habits need careful management to reduce risk.
Stages of Healing: From Pain to Performance
Like any muscle injury, hamstring recovery follows stages:
- Acute Phase (0–72 hours):
- Pain, swelling, and limited mobility.
- Goal: Protect the muscle and manage pain.
- Sub-Acute Phase (1–3 weeks):
- Scar tissue forms. Pain decreases, but mobility is restricted.
- Goal: Begin gentle mobility and early strengthening.
- Remodeling & Return-to-Sport Phase (4+ weeks):
- Muscle fibers realign and strengthen.
- Goal: Restore eccentric strength, speed, and sprint mechanics before full competition.
Skipping or rushing through a stage often leads to reinjury, especially in athletes eager to return.
Physiotherapy Strategies for Pain Management and Recovery
Acute Phase Physiotherapy (0–72 hours)
- Relative rest: Avoid sprinting or explosive movements, but do not completely immobilize.
- Ice, compression, elevation: Reduce swelling and pain.
- Gentle pain-free mobility: Maintain circulation and prevent stiffness.
Sub-Acute Phase (1–3 weeks)
- Stretching and mobility drills: Restore range of motion.
- Isometric and concentric strengthening: Start with low load, progress gradually.
- Manual therapy: Soft tissue release and modalities for pain relief.
Late-Stage Physiotherapy (4+ weeks)
- Eccentric strengthening: Nordic hamstring curls, Romanian deadlifts, single-leg bridges.
- Plyometrics and sprint mechanics drills: Mimic the demands of track performance.
- Neuromuscular retraining: Correct faulty patterns to avoid reinjury.
Return-to-Play Criteria for Track & Field Athletes
Before stepping back on the track, athletes should pass:
- Strength symmetry tests: Equal hamstring strength on both sides.
- Eccentric strength testing: Using tools like the Nordic board.
- Sprint drills at 95–100% intensity with no pain.
- Functional movement assessments: Single-leg hops, bounds, and acceleration drills.
Meeting these objective criteria helps ensure performance readiness and injury resilience.
Prevention Strategies for Sprinters and Jumpers
Preventing hamstring injuries is as important as treating them. Evidence supports a multi-pronged approach:
- Dynamic warm-ups: Leg swings, skips, activation drills.
- Eccentric training: Nordic hamstring exercises can reduce injury rates by up to 50%.
- Core and pelvic stability drills: Improve sprint mechanics.
- Gradual load progression: Increase training volume by only 5–10% per week.
- Recovery habits: Prioritize sleep, nutrition, hydration, and soft tissue care.
Conclusion: Returning Faster, Stronger, and Injury-Free
A hamstring injury is a setback that can become a comeback with the right approach. Through focused pain management, progressive strengthening, and sprint-specific retraining, athletes regain strength and confidence. Prevention then becomes part of daily training to avoid future injuries.
